Notes. ⁽¹⁾Key to photometric data set (PD): 2M – based on 2MASS photometry (Cutri et al. 2003); BD – based on BDA (Mermilliod 1992); DA – based on DANCe (Bouy et al. 2013); G3 – based on Gaia EDR3 photometry (Gaia Collaboration 2021a); TY – based on Tycho photometry (Høg et al. 2000). ⁽²⁾Aimed at deriving empirical isochrones, and therefore only a comparison to theoretical isochrones, but no formal isochrone fitting.
